What should you be prepared here?

In the context of the German traffic rules, the question you answered likely relates to road conditions that can affect vehicle handling and braking.

When you encounter certain conditions, such as wet or slippery roads, it is crucial to extend the braking distance and understand how these conditions can negatively affect driving stability.

A combination of choices indicating that drivers should be prepared for both extended braking distances and reduced stability helps highlight the importance of precaution under adverse conditions. It underscores that not only should one anticipate a longer time and distance needed to stop, but also be aware that the vehicle may not respond as usual, which is critical for maintaining control and ensuring safety on the road.

In practice, this means adjusting your speed and driving style to suit the conditions to prevent accidents.
